An operational sequence including a cleaning of a processing device shifting to the standby state in the process of shifting from a printing operation to a standby state of a liquid electro-photographic device of a tandem type is performed well. A processing device has a squeeze roller for performing removal of residual liquid developer from an image formed on a photoconductive belt 2 and for forming an image into a film and is removed in order that the squeeze roller 6 shifts from the state having a clearance from the photoconductive belt 2 to the state being pressed against the photoconductive belt 2 for performing a removal of the liquid developer remaining on the squeeze roller 6 to the photoconductive belt 2 in sequence when the image forming operation is finished after cleaning the liquid developer adhered on the squeeze roller 6, and the removal proceeds sequentially from a processing device on a downstream side of a traveling direction of the photoconductive belt 2. And the processing device is retracted in order that the squeeze roller 6 shifts from the state having a clearance from the photoconductive belt 2 to the state pressed against the photoconductive belt 2 after performing the removal of the liquid developer remaining on the squeeze roller 6 to the photoconductive belt 2 in sequence, and retraction proceeds sequentially from a processing device on a downstream side before the dirt of the liquid developer removed from the squeeze roller of the processing device on an upstream side to the photoconductive belt 2.
